Cloned server unable to join domain

I'm building 2 servers, both Windows 2012R2. I've created each [Virtual] machine in VMware by cloning a pre-built template for Windows 2012R2.

The first server was setup as an Active Domain controller. The second is going to be an Exchange 2013 server.

When attempting to join the Exchange machine to the domain, I receive the following error:
The following error occurred attempting to join the domain "MyDomain".
The domain join cannot be completed because the SID of the domain you attempted to join was identical to the SID of this machine. This is a symptom of an improperly cloned operating system install. You should run sysprep on this machine in order to generate a new machine SID.

Following the instructions to this link, I was unable to see any duplicates.
